TRIMMING ATTACHMENT FOR SEWING MACHINES Filed Sept. 10, 1957 INVENTORAfar/v19 Fez Z Y ATTORNEY Patented Jan. 11, 1938 UNITED STATES PATENTOFFECE TRIMMKNG ATTACHMENT FOR SEWING 1 Claim.

My present invention relates to attachments for sewing machines, andparticularly to the type adapted for guiding a series of tapes to besimultaneously sewn.

The principal object of this invention is to provide a novel andimproved attachment for sewing machines, to guide a series ofdifferently colored tapes, superimposed longitudinally one on the otherto be sewn simultaneously to form a decorative trimming.

Another object hereof is to provide a novel and improved attachment ofthe character described for guiding a series of difierently coloredtapes in longitudinal superimposed relation, the margins of eachsuccessive tape to lie exposed beyond the margins of each precedingtape, and whereby all tapes are simultaneously sewn onto a fabric to betrimmed thereby, in a single operation.

A further object hereof is to provide a novel and improved device of theclass mentioned which is cheap to manufacture, simple to use and whichprovides economy in the performance of the work to be accomplished.

Other objects will become manifest as this disclosure proceeds.

In the accompanying drawing, forming part of this application, similarcharacters of reference indicate corresponding parts in all the views.

Fig. 1 is a perspective view showing an attachment adapted for amulti-needle sewing machine which follows the teachings of my presentinvention.

Fig. 2 is a section taken at line 22 in Fig. 1.

Fig. 3 is a diagrammatic representation in side view, showing the mannerin which my present invention is used.

Fig. 4 is a similar diagrammatic representation in front view.

Fig. 5 shows character of the work accomplished with my presentinvention, namely, a trimming done in one operation which heretoforerequired many single runs.

In the drawing, the numeral 15 designates generally a presser foot for amulti-needle sewing machine I6, the plate ll of which foot is providedwith the apertures, collectively designated by the numeral 18, forpassage of the needles of said machine to their respective shuttles. Infront of said apertures I8, and transverse the direction of motion ofmaterial sewn by the machine It, the plate I! of said foot 15 isprovided with a series of substantially parallel slots I9, 20 and 2! forthe respective passage and guidance therethrough of the differentlycolored tapes 22, 23 and 24 unwinding from off to be sewn on to thematerial 39, as a trimming the rolls 25, 26 and 21 respectively. Thesize of these slots is greater as their position is further away fromthe foot mounting means indicated generally by the numeral 28, which isof any ordinary construction for attachment to the 5 shank 29, and theextremities of any of these slots, lie within the extremities of thenext larger slot. Also the extremities of each of said slots extendbeyond different pairs of needles, so that in particular, the middlepair of needles 30 and 3|, passing through the needle holes 33 and 34,would sew the longitudinal edges of tape 22 and all material beneathsaid tape, and the pair of needles 35 and 36, which have the first pairof needles mentioned intermediate them, would pass thru needle holes 3'!and 38, and would sew the longitudinal edges of tape 23 and all materialbeneath said tape, and so on, depending upon the number of tapes, whichmay be two or more,

for the latter. It is evident, that such trimming would have theappearance as is illustrated in Fig. 5, and of course is accomplished ina single operation. When any single length of trimming is complete alongthe material 39, the tapes 22, 23 and 24 are simultaneously severed by asingle shears out behind the presser foot l5, whereby a new run may becommenced without any further manipulation or setting of the trimmingtapes until their respective rolls are consumed. It is evident that asingle line of stitches 40 would be sufficient to accomplish theassembly, in which event, a single needle machine need be used. Ofcourse, in such instance, to be a practical trimming, the difierence inwidths of the several tapes should be small. When such difference isappreciable, it is preferable that the longitudinal edges of each tapebe sewn as shown in Fig. 5.

This invention is capable of numerous forms and various applicationswithout departing from the essential features herein disclosed. It istherefore intended and desired that the specific embodiments shownherein shall be deemed illustrative and not restrictive, and that thepatent shall cover whatever features of patentable novelty exist in theinvention disclosed; reference being had to the following claim ratherthan to the specific description herein to indicate the scope of thisinvention.

I claim:

A trimming attachment for a multi-needle sewing machine, comprising asubstantially horizontal plate member adapted to serve as the presserfoot of the machine, and provided with a number of slots of differentlengths adapted to receive and guide therethrough tapes of respectivelycorresponding widths in superimposed re lation whereby the longitudinaledges of any of the superimposed tapes lie intermediate the 1ongitudinaledges of the tape immediately beneath it, and means to mount said plateonto the presser foot spindle of the sewing machine; said plate beingalso provided with a series of apertures to permit passage of theneedles of the machine to their respective shuttles; said apertureslying respectively in the path of travel of the respective tapes; eachaperture being adjacent a 10ngitudinal edge of one of the tapes, wherebysaid tapes may be sewn one on to the other along their longitudinaledges by a single run through the machine. v
